I don't know I've been to that particular liberal parish before and after they got a priest that wouldn't enable them. They seemed to get back in line. The main thing wasn't that the homily had changed since even liberal priests will usually give a more or less doctrinally sound homily, but that everything they were being told in the various bible studies, ACC, and CCC was no longer liberally minded.
I think people should search out their own answers rather than let a pastor “do their thinking for them.” I don’t know that people pay that much attention to sermons.
